Frequently Asked Questions

What is Passkey?

A passkey is a modern, secure way to log in to apps and websites without needing a traditional password. Instead, it uses biometric authentication (like your fingerprint or face ID) or a PIN on your trusted device.

Is KEYRING SMART Wallet safe?

Yes, it is! The KEYRING SMART Wallet uses Passkey as its primary security method. This means that to perform any transaction, users must authenticate themselves through their Passkey—such as a fingerprint, Face ID, or the PIN code of their trusted device.

Even if your device is lost, no one else can access your KEYRING SMART Wallet unless they have your Passkey. This ensures that your funds and wallet remain secure, providing peace of mind in protecting your assets.

Why do I have to register an image and nickname when creating an account?

You don’t have to! This step is optional during the account creation process. It’s part of a feature we call the Address Book NFT.

Here’s how it works:

• If you choose to provide an image and nickname, we’ll use this information to create a personalized NFT for your account.

• This NFT helps you customize your account and makes managing it more convenient.

Additionally, it enhances transaction clarity: other KEYRING SMART Wallet users can easily identify you during transactions, reducing errors when entering recipient details.

So while it’s optional, it’s a great way to personalize your experience and streamline your wallet usage!

What is an Address Book NFT?

The Address Book NFT is a feature that personalizes your account by turning your image and nickname into a unique NFT.

This NFT acts as a profile for your wallet, making it easier for others to identify you during transactions and reducing errors when sending funds.

It’s an optional but practical way to enhance your wallet’s usability and identity on the blockchain.

Why sometimes I have to confirm via Passkey twice, and other times it's only once?

The number of Passkey confirmations depends on the relationship between the token being sent and the gas token's blockchain.

• Single Passkey Verification: This happens when the token you’re sending and the token you’re using to pay the gas fee are on the same blockchain.

• Double Passkey Verification: This is required when the token you’re sending and the gas fee token are on different blockchains.

This ensures extra security and clarity for cross-chain transactions, minimizing errors and keeping your assets safe.

Can the same account be used on multiple devices?

Yes, you can use the same account on multiple devices, but the devices must be compatible with one another. Here's how it works for different platforms:

• For iOS Devices: If your devices share the same iCloud account, your Passkey is stored and synced through iCloud. This allows seamless login to the same KEYRING SMART Wallet across multiple Apple devices.

• For Android Devices: Similarly, if your devices use the same Google account, your Passkey will be synced via Google services. This enables you to access your wallet on multiple Android devices.

• For Windows PCs: Windows PCs do not currently support Passkey sharing across devices. If you create a KEYRING SMART Wallet on a Windows PC, it is likely tied to that specific device and may not be accessible from others.

To maximize your experience with KEYRING SMART Wallet, we recommend creating your account on a mobile device.

Can I use any ERC-20 Token as a Gas Token?

Not all ERC-20 tokens are supported. Currently, KEYRING SMART Wallet supports ERC-20 tokens on the following five chains:

• Ethereum

• Optimism

• Binance Smart Chain (BSC)

• Polygon

• Arbitrum

Additionally, whether a token can be used as a gas token depends on the initial configuration set by our partners. Ensure the token you wish to use is compatible with these chains and meets the specific requirements for gas payments.

If I delete my cache on my device, will I lose my account?

No, your account is safe. The KEYRING SMART Wallet is linked to your device’s Passkey, not its cache or browsing history. Deleting your cache will not affect your wallet.

However, be cautious: since the wallet relies on your Passkey, deleting or changing your Passkey may result in losing access to your wallet. Always ensure your Passkey is secure and intact.

Can I delete my wallet account?

No, you cannot delete your KEYRING SMART Wallet account as long as the Passkey remains the same. If you change the Passkey you used to create the wallet, you will no longer be able to log in to it.

However, the wallet itself is not deleted; you simply lose access to it because the Passkey is the key to unlocking it. Always ensure your Passkey is secure and kept safe.
